It is tantamount to a family on a $30,000 a year budget putting about $100 or less into silver bullion. The article, 2nd paragraph, notes the trade balance between the two at $30 billion. China's GDP is on course to exceed our own in a few years so that means their GDP is probably $13 trillionish right now? 30 billion out of 13 trillion is $1/433 so the family with $30,000 its them spending $69 on silver or another prep.
Its worth watching to see if the continues or if other countries start doing it more and more. I'd be more concerned if they were promoting a UN currency in place of the dollar.
